This will get you what you need to convert images into text on the command line.

First you'll need to convert files into TIF (Tagged Image Format File) format to be able to feed into Tesseract.
This is meant to be a high quality image to be scanned by Tesseract ocr.

Convert to TIF

convert image.png -resize 400% -type Grayscale image.png.tif

Convert to text

tesseract -l eng image.png.tif image.png

Vola! The text in the image is stored in the output file image.png.txt.

Emacs

With this, I'd like to build an emacs plugin that runs tesseract on any images I have open in a buffer. (images in emacs buffer render as an image).
So that, a new buffer window would either replace or open side-by-side with the text extracted from that image,
